Short presentation
Ecology of mire plants and bryophytes: My research focuses on peatland ecology and covers community structure, competition, niche relations, ecophysiology, reproduction, dispersal and metapopulation dynamics in bryophytes. Sphagnum species (peat mosses), rich fen bryophytes and epiphytes are the main study objects. I retired in 2019, but maintain some research.
